Too high a diet in carbohydrates creates nasal conjestion and asthma. When winter comes and there is less sun we all have a tendency toward eating more carbohydrates and thus comes the common cold, which is nasal and chest conjestion with phlegm. To come into balance, eat less sugar and carbohydrates, whole grains, vegetable and fish are the median balance foods.
Higher energy and weight loss occur through the increase of meats and the reductions of sugars, fruits and refined carbohydrates.
I'm currently suffering with a sinus cold while on a ketogenic (very low carbs) diet, so this information (although good advice) doesn't apply to all sinus cold.
